CBSE has moved steadily towards competency-based assessment, testing whether you can apply a concept, not just recall it. That shift shows up directly in how the Class 10 Science paper is built. Here is the structure to expect, and where to check the exact scheme for your exam year.
The CBSE Class 10 (CBSE 10th) Science exam pattern is typically an 80-mark theory paper in five sections: MCQs (including Assertion-Reason) at 1 mark, very short answers at 2, short answers at 3, long answers at 5 and case-based questions at 4 marks, alongside 20 marks of internal assessment. Always verify against the current-year CBSE sample paper.
What is the CBSE Class 10 Science exam pattern?
In recent years the Science theory paper has followed a five-section structure. This is the commonly published pattern; CBSE releases the official scheme in its sample papers each year, so confirm the current one:
| Section | Question type | Marks each | Typical count |
|---|---|---|---|
| A | MCQs, including Assertion-Reason | 1 | 20 |
| B | Very short answer (VSA) | 2 | 6 |
| C | Short answer (SA) | 3 | 7 |
| D | Long answer (LA) | 5 | 3 |
| E | Case-based / source-based | 4 | 3 |
These add up to 80 marks for the theory paper. The remaining 20 marks come from internal assessment, which your school conducts.
What is internal assessment?
Your final result combines the board exam with internal assessment conducted by your school (periodic tests, practical work, portfolio and subject enrichment activities). Your school will confirm the exact components for Science.
What kinds of questions appear in each format?
- MCQs: objective questions on concepts, application, numericals and diagrams. See Science MCQ practice.
- Assertion-Reason: a few MCQs where you judge two statements and their link. See the guide.
- VSA and SA: brief explanations, reasons, short numericals and reactions.
- LA: fuller explanations, multi-step numericals or diagram-based answers.
- Case-based: a passage or data set followed by linked sub-questions. See how to solve them.

Why does the competency-based shift matter for how you prepare?
CBSE has increased the share of questions that ask you to apply concepts to unfamiliar situations. Memorising definitions and formulas is necessary but no longer sufficient. The best preparation is practising with questions that force application, which is exactly what recent PYQs and case-based questions do.
Where should you check the exact current-year scheme?
- The official CBSE sample question papers and marking scheme on CBSE's academic website, published ahead of each academic year.
- Your school's subject teachers, who receive CBSE circulars on any changes.
The counts above reflect recently published patterns and may change; do not rely on a previous year's split.
How do you prepare for this pattern?
Practise every format in its real form, chapter by chapter first, then in full papers. The step-by-step plan is in how to prepare Class 10 Science for boards, and the PYQ method is in how to practise PYQs.

Frequently asked questions
How many marks is the CBSE Class 10 Science paper?
The theory paper is typically 80 marks, with 20 marks for internal assessment. Confirm on the current-year CBSE sample paper.
How much time is given for the Class 10 Science exam?
The theory paper is typically three hours. Check your admit card and the CBSE circular for your year.
Are case-based questions compulsory?
They form a dedicated section in the paper, so they are part of the exam you should prepare for. Check the current sample paper for choices and internal options.
Where can I find the official marking scheme?
On CBSE's academic website alongside the sample question papers for your exam year, and through your school.
What is the CBSE 10th Science exam pattern?
The CBSE 10th Science theory paper is typically 80 marks across five sections: A (MCQs, 1 mark), B (very short answer, 2 marks), C (short answer, 3 marks), D (long answer, 5 marks) and E (case-based, 4 marks), plus 20 marks of internal assessment. Confirm on the current-year sample paper.
What does SQP mean in CBSE?
SQP stands for Sample Question Paper. CBSE publishes one for each subject ahead of the exams so you can see the current pattern, question types and marking scheme.
